Write a multiway if-else statement that classifies the value of an

int variable n into one of the following categories and writes out an

appropriate message:

n < 0=”” or=”” 0=”” ≤=”” n=”” ≤=”” 100=”” or=”” n=””> 100

The Correct Answer and Explanation is:

Here is a correct multiway if-else statement in C++ (also applicable in C or Java with minor adjustments) that classifies an integer variable n:

#include <iostream>
using namespace std;

int main() {
    int n;
    cout << "Enter a number: ";
    cin >> n;

    if (n < 0) {
        cout << "The number is less than 0." << endl;
    } else if (n >= 0 && n <= 100) {
        cout << "The number is between 0 and 100 (inclusive)." << endl;
    } else {
        cout << "The number is greater than 100." << endl;
    }

    return 0;
}

Explanation (Approx. 300 words):

In programming, especially when using decision-making structures, a multiway if-else statement is used to handle multiple conditions based on the value of a variable. In this case, we want to classify the value of an integer variable n into one of three distinct categories:

Less than 0
Between 0 and 100 inclusive
Greater than 100

The program begins by prompting the user to enter a value for n. Using the cin statement in C++, we capture this input.

The first if condition checks if n < 0. If this condition is true, the program executes the block under this condition and outputs “The number is less than 0.”

If the condition n < 0 is false, the program checks the next condition with else if (n >= 0 && n <= 100). This condition verifies if n is in the range from 0 to 100, including both endpoints. If this condition holds true, the message “The number is between 0 and 100 (inclusive)” is printed.

Finally, if neither the first nor the second conditions are true (meaning n must be greater than 100), the else block is executed. It prints “The number is greater than 100.”

This approach ensures that only one of the three conditions will be executed, thanks to the mutually exclusive nature of the checks. This is a clear and efficient way to categorize numeric data using a multiway if-else structu
